Oh i forgot to describe the trains. It's at Copenhagen Central Station in Denmark ..the ones in the pictures are trains that go through different regions within the country, and some of them also crosses bridges to the other Island like Fyen and Jutland.
(current picture: Hillered Station)
The small train in this picture is part of "lokal banen" and only goes through northern Sealand,
The big red train on the photo is called "S-tog" which means an S-train, and I haven't got a clue why they call it that... the train is parked btw. passengers are not allowed on that track. The non-parked S-trains are on the other side of the bridge.
